Thai Digital Arrival Card (TDAC): Everything You Need Before Entering Thailand

When I first arrived in Bangkok back in 2018, I remember filling out the old paper arrival card while balancing a tray of airplane food on my knees. My pen didn’t work, my passport kept sliding onto the floor, and by the time we landed, I had already made three mistakes. Fast-forward to 2025 — and Thailand has finally ditched the paper chaos in favor of something smarter: the Thai Digital Arrival Card (TDAC). If you’re planning a trip to Thailand in 2025, there’s a new box to tick before takeoff. Starting May 1st, 2025, all foreign travelers will need to complete the TDAC online before arriving in the country. No more scribbling on forms mid-flight — this change is part of Thailand’s push toward a fully digital immigration system.

Official TDAC Introduction Video

Watch the official introduction to Thailand’s Digital Arrival Card — This video, published by the Thai Immigration Bureau, explains how the TDAC works and what travelers need to prepare before arriving in the country.

What is the TDAC, exactly?

Purpose and benefits

The TDAC is Thailand’s new mandatory online arrival registration system. Think of it as a virtual replacement for the old paper form you used to fill out on the plane. Instead of fumbling with a pen at 30,000 feet, you now fill out a short form from your phone or laptop 24–72 hours before your trip. It’s fast, free, and crucial if you want to avoid surprises at immigration.

Who needs to fill it out?

Types of travelers concerned

Short answer? Everyone who isn’t Thai. Whether you’re flying in for a beach holiday, coming for business, retiring under a long-stay visa, or simply transiting through Bangkok for a few hours — the TDAC applies to you. No exceptions (yet).

Why is this happening?

Goals of the digital transition

Thailand’s moving toward a streamlined, paperless system to improve security, reduce wait times, and make life easier for travelers and border officers alike. The TDAC allows immigration to pre-screen passengers and process arrivals faster. Plus, it’s one less form to forget at home.

How do I complete the TDAC?

Step-by-step process

Here’s your mini checklist to get it done in under 10 minutes:

1. Go to the official TDAC portal: tdac.immigration.go.th
2. Enter your passport and personal info
3. Fill in your flight number, date of arrival, and address in Thailand
4. Upload a passport photo or scan (if required)
5. Submit and save your QR code confirmation

Tip: Screenshot your QR code or save it in your email. You’ll need to show it at immigration on arrival.

What if I forget?

Consequences of missing the TDAC

Showing up in Thailand without completing the TDAC could mean long delays at immigration — or worse, being denied entry. Airlines might also refuse boarding if your arrival card isn’t submitted ahead of time. Don’t risk it. While the TDAC simplifies entry, it’s wise to stay updated on the overall travel situation in Thailand, which can change quickly due to political or security reasons. Be especially cautious of unofficial websites that charge a fee or ask for personal data. For more tips on avoiding this and other common traps, read our full guide on Thailand scams in 2025.

Any exceptions?

Current exemptions and updates

As of now, the rule applies to all foreign nationals. Thai citizens are exempt, and there may eventually be exceptions for diplomats or border commuters, but nothing official has been announced yet.

TDAC vs. visa — what’s the difference?

Comparison with traditional visa requirements

The TDAC is not a visa. If you’re from a country that requires a visa to enter Thailand, you’ll still need to apply for that separately. The TDAC is simply a new arrival protocol — like filling in your passenger locator form — and it’s required whether you need a visa or not.

What makes this good news?

Advantages of the new system

Despite being a new task on your pre-travel checklist, the TDAC is actually a smart move. It speeds up border control, removes paperwork, and reduces errors. This new formality is a key part of the government’s strategy to modernize and revive tourism in Thailand for 2025, reflecting a growing commitment to a more efficient and secure infrastructure.

Before you fly: final tips

• Submit your TDAC at least 48 hours before you travel
• Double-check your info before hitting “submit”
• Keep your QR code handy — print or digital
• Ask your airline if they check for TDAC at check-in
• Don’t assume it’s optional — it’s not!
